DERRICK-ISWINGING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 749,352, dated January12, 1904.

Application filed January 31, 1901. Serial No. 45,402. (No model.) V

To a. whom it may concern: 7

Be it known that I, CHARLES A. BAEoHroLi), a citizen of the UnitedStates, and a resident of Westfield, in the county of Union and State ofNew Jersey, have invented'a new and Improved Derrick Swinging Mechanism,of which the following is a full, clear, and exact description.

My invention relates to an improvement in devices particularly designedfor use in swinging a derrick, and comprises certain novel mechanisms bywhich a drum may be made to reverse its direction while receiving itspower from a shaft revolving in a constant direction.

My invention further comprises the combination of'the various parts ofthe engine and the derrick with said drum and its reversing mechanism.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of my device connected with an engine. Fig. 2 isan end ele vation of the same. Fig. 3 is a longitudinal taken upon theline 3 3 of Fig. i. Fig. 4 is a cross-section'taken upon the plane whichincludes the journals of the bevel-pinions, and Fig. 5 shows thecombined winch-head and pinion. My device is primarily intended as anattachment to hoisting-engines and to be used for the reception of arope or cable which leads to opposite sides of a bull-wheel placed uponthe mast of a derrick, whereby the derrick may be swung into any desiredposition.

It is'ev'ident that the device may be used 1 for other purposes thanswinging derricks and 40 also may be built as a component part of theengine, and I do not, therefore, wish to be understood as limitingmyself to the use of the device for this particular purpose nor tothedevice when built as an attachment.

In the drawings, A represents a drum of any type of hoisting-engine. Theshaft A of this drum, which is usually non*reversible,'is provided withan additional pinion a, which jacent end of the drum.

meshes with a gear B, mounted upon the shaft O of my device. A form ofconstruction whichis much preferred by me is partially shown in Fig. 1and a detail thereof shown in Fig. 5. The pinion or gear a; is thereinmade as a part of the winch-head a. he shaft C is supported in suitablebearings in the frame C and is rotated constantly in one direction bymeans of the connection through the gears a and B with the shaft A" ofthe hoisting-engine. I have shown this power connection as with one ofthe drum-shafts. Itwill, however, be understood that the connection maybe made with any convenient portion of the hoistingengine.

Upon the shaft O is loosely mounted a drum D, upon one end of which isformed a bevel gear-wheel d. Mounted upon this shaft and facing saidbevel-gear is a friction-disk E, which issplined to the shaft so that itwill turn therewith, butmay slide lengthwise thereof. This disk isprovided with friction-blocks e, which enter a groove f in aloosely-mounted friction member or disk F, which lies between thefriction-disk E and the end of the drum. The outer surface of thisfriction-disk receives a brake-band G or is otherwise engaged by anysuitable brake mechanism, so that the rotation of the disk F may beprevented when desired. The friction-disk has a flange F projectingtoward the drum and preferably terminating closely adjacent to theradial flange d of g the drum, so as to close the space lying betweenthe body of the friction-disk F and the ad- A cup-shaped member is thusformed.

A bevel-gear H, corresponding in size with the bevel-gear d'of the drum,is fixedly se- V cured to the shaft C next to the friction-disk F andbetween the same and the end of the drum. A spider or frameI is looselymounted upon the shaft between the bevel-gear H andthe end of the drumand preferably snugly filling the space between the same. This spider orframe has its periphery secured to suitable bearing-surfaces upon thecup-shaped frictiondisk F by means of bolts 2' or other suitable means,so that when the two are secured together they form substantially onemember. This spider has openings 1 opposite each other and adapted toreceive the bevel-pinions J. Said pinions are mounted upon pins orjournals K, which have their inner ends screwed or otherwise securedinto the hub of the spider 1. Locking set-screws Z2 are also shown. Thespider or frame I, together with the friction-disk F, thus constitute apinion-carrier, which is provided with friction-surfaces 'engaging,respectively, with the friction member e and the brake G. These pinionsmesh with both of the bevel-gears H and d. Oilchambers k are provided inthese pins or journals, extending lengthwise the axis thereof andreaching to the shaft C. Radial oil-openings 7c are provided, reachingto the bearingsurface of the pinions J thereof. The axial hole extendsto the outer end of the pin and is closed by means of a screw L, whichis threaded in an opening in the flange E, which lies in line with theaxis of said pin or journal. By removing one of these bolts thepinion-journal,as well as the bearing of the spider upon the shaft, maybe oiled, and the oilingopening may then be closed by the insertion ofthe bolt. Any suitable means are provided by which the friction-disk Emay be moved, so as to be engaged or disengaged from the friction-diskE. A spring M of customary form is provided for pushing said disks outof contact.

The reversal of the drum is secured by the means described in thefollowing manner: If the brake G be loosened upon the disk F and thefriction-disk E be forced into engagement with the disk F, then the diskF is forced to revolve with the disk E-that is, with the shaft C. Thiscarries the spider I and the pinions J carried thereby around the shaftat the same speed. Consequently as they engage with the bevel-gear H,which is secured to and rotates with the shaft, there is no rotation ofthe pinions upon their journals and they simply have amotion oftranslation about the shaft A and serve merely as levers connecting thebevel gears H and d. Consequently the drum D is made to rotate with theshaft and at the same speed. If, however, it is desired to reverse thedirection of the drum, this is done by freeing the friction-disks E andF and by applying the brake to the disk F, so as to prevent or check itsrotation. When this occurs, the spider carrying the pinions is eitherheld stationary or is permitted to rotate with the shaft at a lessspeed. Consequently there will be a rotation of the pinions J upon theirshafts, and this motion will be communicated to the drum D, causing thesame to rotate upon the shaft and in the opposite direction therefrom.The speed of rotation of the drum D may be-made to vary from nothing tothe same speed as the shaft in either direction by either setting thefriction devices up hard or by applying them lightly, so as to permitslipping of the parts.

The mechanism herein shown for operating the friction-disk E is of theold and well-known construction, which employs a pin N, movable within aslot extending lengthwise the shaft, and the pin-actuating rod N, whichlies within an axial bore in the shaft and at its outer end passesthrough a yoke N with which it is threaded, so that by means of rotationof the rod N the friction-disk E may be pressed against the disk F. Tothe outer end of the rod N is secured the arm or lever O. This being anold and well-known construction which is most frequently employed forsuch purpose, fuller description and illustration are unnecessary. Anyother friction-applying device may be substituted therefor.

Alongside of and parallel with the axis of the drum is placed a shaft P,to which an operating-lever P is connected. This shaft has two arms pand p, to the first one of which the friction-operating arm 0 isconnected by means of a link 0 and to the other of which the brake-bandG is connected. These parts are so arranged that the friction is appliedby movement of the lever in one direction, while the brake is applied bythe movement of the lever in the opposite direction, while in thecentral position of the lever neither brake nor friction are in use.

It will be seen that my device is very compact and simple in itsconstruction and may be operated to swing the derrick or to reverse theaction of whatever mechanism the cable leading from the drum isconnected with by the simple operation of throwing a lever in onedirection or the other from its central position.

The device when mounted upon an independent frame may be attached to anyform of engine. Whether mounted in this manner or built into theengine-frame, it provides a reversible drum in connection with anon-reversing engine. The rope used with the drum D is placed thereon soas to wind upon one end and to wind off of the other. If desired, thedrum may be shortened and made as a winch, so that only a few turns willbe needed upon the drum at one time. I

The device is well adapted for all uses where a reversible drum isdesired in connection with a non-reversing engine.
